Supplementing with vitamins has become extremely important for overall well-being and longevity. The food we grow and eat today has fewer nutrients than it did 20, 30, 50 years ago, so we cannot depend on food sources alone.

Fresh fruit and vegetables, fatty fish, whole grains, and other nutritious foods contain way less macro and micronutrients than we need on a daily basis. Our bodies need vitamins and minerals for all processes to run smoothly and stay optimized, reducing the risk of heart disease and other health conditions.

Unfortunately, due to poor nutrition and lifestyle choices, chronic stress, and environmental toxins, the majority of people are dealing with vitamin deficiencies. Luckily, we have some amazing vitamin brands out there, ready to help us get back on track.

10 Best Vitamin Brands On the market in (September. 2023)

What Vitamins Should You Take Daily?

The majority of people are lacking in B vitamins, vitamin D[1], vitamin C, and even vitamin E. IF you’re following a vegan or vegetarian diet[2], you might also be lacking vitamins K2 and B12. If you’re pregnant, you need to focus on B12 and folic acid. It’s important to try and add foods that are rich in these vitamins into your daily diet, but that’s an extremely difficult task in today’s busy and hectic world. 

This is where taking a vitamin or mineral supplement is helpful. It delivers a large number of micronutrients[3] in just a few little pills or capsules, and it’s helping optimize our digestive system, immune function, hormone health, and so much more.

Most of the vitamin brands are generic, meaning they aren’t specifically tailored to you and your needs. Therefore, if you’re interested in diving deeper, ask your doctor or naturopath to order a micronutrient panel so you know exactly what dose of which key nutrients and vitamins you actually need.

How To Choose The Best Vitamins?

When searching for the best vitamin brand for you and your specific needs, there are a few important things to pay attention to. When you enter a health food store, chances are you’ll be overwhelmed with a huge number of brands claiming their products are the best. Here is what to look for.

Ingredients

High-quality ingredients should be at the top of your list. Many brands now offer information on sourcing and transparency throughout the entire supply chain process. The more details you can find, the better, as you’ll know exactly where their ingredients come from.

Third-Party Testing

Vitamin brands that allow third-party testing[6] basically invite you to take their supplements into any independent lab and ensure yourself of their potency, purity, and quality. This really showcases their confidence in their products and dedication to bringing you the best ingredients possible.

Certifications

Choose brands with certifications such as Certificate of Analysis (COA)[7], United States Pharmacopeia (USP),  #1 Pharmacist Recommended, NSF International, or the Consumer Lab seal. These verify that the product contains the ingredients that are on the label. They also ensure that the brand’s products don’t have any potentially harmful ingredients, artificial fillers, preservatives, colors, or additives.

Access To A Registered Dietitian Nutritionist

Choose a brand that offers you the chance to consult with an expert who can help answer all of your questions to better decide which products are right for you. This way, you can get a more personalized approach even if the brand doesn’t make custom-tailored supplements.

Personalization

If possible, look for a brand that will personalize the supplement formula specifically for you. They usually do it after you complete an online questionnaire which gives them more insight into your particular lifestyle, health goals, and needs.

Final Thought

Even if you’re keeping a very healthy diet with plenty of fruit, leafy green vegetables, lean protein, healthy fat, and whole grains, chances are, you’re still vitamin and mineral deficient. Supplements are here to help optimize your system and push your body to efficiently cleanse toxins and heavy metals, utilize nutrients for fuel, and repair cellular damage. Choose brands with high-quality, clinically proven, third-party tested ingredients, and feel good knowing you’re doing something amazing for your overall health and longevity.
